In this game the Vienna, Paulsen variation was played but despite TheKing using the Master (HIARCS book) it’s move 3.g3 is considered dubious by HIARCS and as the comment states, theory prefers 3.Bc4. But Maia throws in a novelty so all even on this score.

The turning point in this game is from this position:

White’s Bishop on b7 is under attack from Black’s Rook. Here, TheKing retreated with 15.g2 which seems strange when the suggested attacking move of 15.d5+ would seem more natural. Maybe it didn’t like the idea of Black moving Bh3 attacking the Rook? However, Black is in quite a good position with more active pieces and good King-side attacking potential.

Despite having the superior position Maia then made the poor move 15…Qd7?

Had it played 15…Bh3 white must not capture the Bishop as Nf3+ loses the queen! Play might have continued with 16.Bd5+ Needed to fight back! 16…Kh8 17.Nxd4 Remove the troublesome knight! 17…Bxd4 and it’s looking very good for Black. This is only 5 ply so definitely within Maia’s sight. From here TheKing took advantage of Maia’s poor moves and announced mate in 8 at move 75.

TheKing did not have a good start in this game but won because Maia made 1 extra mistake and 4 extra inaccuracies. But I think Maia's positional play was better but lacked that little extra to take advantage.

Current score 1 – 0 to TheKing

The English, Bremen System, Keres variation was played with both sides playing some questionable opening moves. Despite that, with the advantage swinging slightly from side to side all was roughly level in the following position where TheKing had just played 18…Nd5:

Here Black has a knight to White’s 3 pawns but material-wise it’s balanced. Maia’s Rook on f6 is under attack from Black’s Knight and Queen so must be moved. Here, Maia played 19.Rh6? which on the face if it looks good considering White’s Bishop and Queen lined up on the a1 to h7 diagonal. However, after 19…Qg5 attacking the Rook again 20.Rh4 Nf6 21.Rf1 Nxe4 and White’s attack is squashed.

Later on in the following position where Maia had just moved 26.Rh4

Here TheKing blunders with 26…Rac8?? Had Maia seen the correct moves TheKing would have been in trouble. Play could have continued 27.Rh5 f5 28.Rxe8+ Rxe8 29.Qf4 Qa4 30.Qg5+ and white has a nice attack on the King:

Alas, this was beyond Maia and also TheKing of course.

In the following position Black has the stronger position with the active Bishop threatening White’s a pawn with white to move:

Here Maia played 34.Rh7?? Why sacrifice the Rook? I thought this kind of blunder had been removed with the addition of the lookahead feature added to the Maia bots. Maybe this is a bug?

Well, the result was inevitable!
In that game Maia made 1 blunder, 5 mistakes and 6 inaccuracies while TheKing managed 1 blunder and 5 inaccuracies. Much better of course but despite Maia’s strange Rook sacrifice it does play positionally well but is unable to make the best of it. TheKing so far is then able to benefit from Maia’s weaker moves.

Current score 2 – 0 to TheKing.

The Alekhine Defence, Exchange variation was played and all was level up to move 12.Bd7:

Here is an example where TheKing makes a poor move – but as often the case in such situations these moves are only be seen by an engine running on much faster hardware. TheKing played 13.Qc1? Better would have been 13.Rc1 considering that White’s c4 pawn is currently attacked by two Knights with the possibility of Black moving Rc8 adding to the threat. Then, at some point Black can advance the King’s Pawn prompting a pawn exchange and then allowing the advance of the Queen’s Pawn adding to the attack on White’s c5 Pawn. White will need to move the Knight on c3 to allow the Queen to defend the Pawn along with the Bishop on e2. Therefore, protecting the Pawn would be best done with the Rook.

A few moves later with Maia playing well we have this position:

Maia had just played 19…exd5. White is up two pawns but is in a very bad position with the Bishop on e2 and the Knight on c3 both pinned, and the Pawn on g4 is threatened by Maia’s Bishop. Here, “TheKing” needs to get “the King” to safety and makes the move 20.Kf1?! Why not castle?

At move 25…Bd6 we have this position:

Maia is in a winning position but is unable to find the winning sequence. The idea briefly is to maneuver the Queen to e6 and eventually force a Queen exchange. This exposes White’s King to attack by Black’s Rooks. However, this line of thought was beyond Maia’s neural knowledge and it could only manage a draw.

This was an interesting game as it shows weaknesses in TheKing’s play at this time control at least, but also shows how dangerous Maia can be!

Current score 2 ½ - ½ to TheKing.

They played the QGD Slav and all was equal up to TheKing’s move 28…Ra8:

A better move as suggested by HIARCS would have been 28…Nd6 attacking White’s Rook and making it difficult for White to protect the pawn on a6. However, Maia is unable to find the best reply of 29.a7 that keeps Black’s Rook on a8, instead moved 29.Rb7? Black responded with 29…Nec5 attacking both the Rook and Pawns a4 and a6. White is a pawn up but the doubled a pawns balance the position. Here Maia played 29…a7? A curious move indeed. Better would have been 29…Rc7 but the played move loses the Rook to a Knight.

A poor move by TheKing and a blunder by Maia followed and the TheKing announced Mate in 7 at move 65.

The statistics show that Maia made 1 blunder, 4 mistakes and 8 inaccuracies whilst TheKing made 2 mistakes and 6 inaccuracies. Well, we did expect TheKing to do well against Maia.

Current score 3 ½ - ½ to TheKing.

The longest game so far and in this match I have been stopping the game at the point of mate announcements. In this game the Caro-Kann, Spassky variation was played but it was not until almost exactly half way through the game did TheKing start to gain and finally win. In fact, at times Maia was playing much better and should have won.

In the following position Maia had just played 21…Rb8?!

The position is dangerous for TheKing with Maia’s pieces lining up for an attack on its King. However, Maia’s move was not the best. 21…Ba3 would have been the better attack, but nonetheless, TheKing needs to be very careful. The Pawn on b2 and Queen on c2 are the main defence against Maia’s onslaught. TheKing moved 22.Ne5?! Better would have been to consider King safety with 22.Ka1
Play continued with 22…Nxe5 23.dxe5 and although Black is down a pawn is in a much better position:


Later on White had just moved 38.Kc2 and Maia with the Black pieces was 2 pawns down but had again achieved a better position after having an advantage and losing it a few moves back! However, as I often say it’s easy for strong PC engines to identify good and bad positions, in this case DH15.3 was looking 23 ply ahead. TheKing with 30 average 30 seconds was achieving around 10 ply, and Maia was limited to 6 ply although had it’s Neural data to assist. Here is the position:

DH15 gives Black an evaluation of around 2.8 over TheKing. Here, Maia played 38…Qc6+? DH15 gives this position an eval of 0.00 (at ply 28). Play then continue with 39.Bc3 and White would not mind exchanging Rooks to ease the pressure. 39…Rc5 Black wants to keep the Rook! 40.Rd8+ and the game is level. I think for Maia to see the full implications and I assume the Neural data was not good enough, it’s 6 ply search was just not enough to see the better move of 38…Bf8 allowing the move Na3+ to follow. So now the game is level until move 43 when TheKing started to get the advantage. Even then it also made poor choices and levelled the playing field before finally kicking into action, also aided by a blunder from Maia at move 73:

TheKing had just moved 73.Kf3 and Maia replied 73…Qc2?? Had it correctly evaluated the position after 6 ply search that actually followed it would have found the exchange of Queens and Whites’s Pawn on e5 to be a winning combination. I think this is where TheKing’s greater search depth coupled with its programmed knowledge is superior to Maia’s more limited fixed 6 ply, and obviously its neural data is inadequate in such positions. That being said, we can see TheKing is not always playing so well and Maia put up a pretty good fight for half the game. Just imagine Maia being able to look further ahead, the result could well be quite different. Anyway, at move 87 TheKing announced mate in 10.

Current score 4 ½ - ½ to TheKing

In one of the shorter games of the match Maia as White started with an unusual opening and also made a huge blunder! TheKing did not make any bad or dubious moves and seized the opportunity. The blunder came very early on at move 7. Here is the position after TheKing had just moved 7.Bd7 Concealed attack on the enemy Queen.

Maia was unhappy with Black’s Bishop on b4 especially as it had previously moved 7…Bd2. To support it’s dislike of Black’s Bishop Maia played the fateful 8.a3?? 6 ply search is just enough to see that White’s Queen will be lost starting with Black’s reply of 8…Nd4 and now the Bishop is attacking the Queen and Black’s Knight on d4 has its eye on the c2 pawn! 9.Qxb4 If axB4 then Whites Queen is lost to the Bishop on d7! 8…Nxc2+ and White loses its Queen!

At move 35 TheKing announced mate in 8.

The score now 5 ½ - ½ is there any point carrying on? Well it’s obvious TheKing is not going to lose, but this match is more about how well or badly Maia plays. It’s unfortunate, but just prior to the last Evo software update adding the book openings, I had played a game with it against TheKing and it achieved an impressive win with a King-side attack TheKing was totally defenceless against! I don’t know if adding the book openings has weakened it’s play? Maybe I just need to play more games between them to witness a similar result. Suffice to say you will not be seeing a game like that in this match. It’s unfortunate that I did not record Maia’s win against TheKing. Note to self, record every game!

Here we are with game 7 where the Alekhine’s Defence, Scandinavian variation was played. There were no blunders or mistakes by either side and an equal number of inaccuracies, so no surprises the game ended in a draw, only the second so far in this match.

Current score 6 - 1 to TheKing

In this game they played the Caro-Kann Defence and neither side achieving greatness with TheKing wining just by making two less inaccuracies according to DH15. That’s not bad going for Maia!
Where one side had a slight positional advantage it required a much deeper search than either were able to manage for them to benefit. The final decision came in how well the end game was managed.

In the following position at move 55 with White to move the endgame database reveals the result is a draw:

Neither engine uses EGDB’s so their moves were down to knowledge and depth of search. In these positions I suspect TheKing has the advantage as it’s not limited to search depth other than by time constraints. It was not until move 66 when TheKing saw a mating sequence in 7 moves.

An interesting game that could have easily ended up in a draw but a win is a win.
Current score 7 – 1 to TheKing

Here we are at the penultimate game with TheKing playing with the white pieces. The King Pawn Nimzowitsch Defence was played.
In the following position Maia had just taken White’s pawn on g4 with 14…fxg4:

TheKing is not in a very good position, his King is somewhat exposed and under threat of more exposure! His pieces are not very active which seems unlike his normal style of play! However, he seems unperturbed by Maia’s attack and shows little concern for the Black Pawn on g4 and played 15.Nd4? Why not take the Pawn!? Meanwhile, Maia carried on with the attack 15…gxh3 and now White is in real trouble! Play continued 16.Nxe6:

So this is why TheKing did not worry about taking the pawn before, but I think this is a case of too much pruning in the search tree as we shall see from the moves that followed. 16…Qh4 17.Nxf8 wins the Rook but this is not looking good for White. 17…Bh5! Very good, attacking White’s Queen but also adding another piece to the King onslaught:


18.Ng6?? TheKing blunders a piece!? What was it thinking or not thinking? 18…hxg6 Maia seizes the gift. 19.f3 which is what TheKing should have played instead of blundering the Knight. 19…Qg3+ How can White escape this? 20.Kh1 the only sensible option. 21…Rf8 another of Maia’s pieces swings into action:

This is looking good for Maia but it’s not simple, requiring a deep search to find the winning path, something beyond the limited search of these machines and myself come to that! In the end the best Maia could achieve was a draw. DH15 has TheKing making 1 blunder, 1 mistake and 5 inaccuracies while Maia had just 2 mistakes and 3 inaccuracies. An interesting and curious game that I thought Maia was going to win. On the other hand, I think TheKing played very badly and deserved to lose but still managed to survive with a three-fold draw. Maia’s inability to win the game is easily explained by the fact that a much deeper search was required to understand the nuisances of the position.

Current Score 7 ½ - 1 ½ to TheKing

Here we are with the final game in the match. In this game the Vienna opening was played and according to HIARCS Chess Explorer and DH15.3 Maia made 2 blunders, 1 mistake and 6 inaccuracies whilst TheKing managed just 2 mistakes and 6 inaccuracies. It’s obvious which engine played better!

Maia’s first blunder came in the following position where TheKing had just played 33…Nc5:

Here, Black may have a slight advantage with more active pieces. Maia’s blunder was with the move 34.f6?? Not concerned with its pawn on d3. On the face of it, Maia’s pawn advance might look promising considering the pawn is backed up by Maia’s Queen and Rook. However, play continued with 34…Nxd3 accepting the pawn offering. 35.f7+?! Maia likes checking. But Black’s reply 35…Kf8 and now White must protect the pawn that is under threat by Black’s Queen on b3. 36.g6 hxg6 another pawn down! 37.Re4 Qxb2? TheKing makes a poor move. Better was Nf4 blocking off White’s Queen. Here is the position so far:

Play continued 38.Rh4?? Maia’s second blunder. It’s no doubt planning Rh8+ 38…Nf4 an now TheKing sees the Knight move to block off the Queen. 39.Rh8+ Kxf7 40.Rh4 Back to where it was just now but another Pawn down. 40…Qxa3 Pawn grabbing by TheKing 41.Rg4 Qb3 41.Rfg1 hoping to take the Pawn on g6 but 42…Qd5 forcing an exchange of Queens. Now Black has the winning endgame! Not straight forward to see for Maia with it’s limited search depth and again evidence in my opinion where TheKing’s greater ply search in endgames is better than the Neural data that Maia has.

Final score 8 ½ - 1 ½ to TheKing.
